Briarthorn and Mageroyal farming
I made this Briarthorn and Mageroyal farming guide to help out players who want to farm the herbs instead of buying them from the Auction House. These two herbs can be found in the same zones, so I combined the Briarthorn farming guide with the Mageroyal farming guide.
You will need a herbalism skill of 50 if you want to pick Mageroyal and herbalism 70 is required for Briarthorn, so you should have at least herbalism 70 before you try to farm these herbs. Below you will find a list of places where I could farm the most Mageroyal and Briarthorn.
Briarthorn and Mageroyal
Hillbrad Foothills - Horde
Hillsbrad foothills is the best place to farm these two herbs. There is just so much herb in this zone. You can find Frozen Herbs at the top of Alterac Mountains but you won't be able to pick those until your skill reaches 125. Frozen Herbs can contain Mageroyal, Briarthorn or Bruiseweed.
Darkshore - Alliance
Darkshore is also a really good place to farm Briarthorn and Mageroyal. Not as good as Hillsbrad but if you are an Alliance player and you can't go to Hillbrad, Darkshore is the best zone.
